The ships were designed as armoured frigates in response to an invasion scare sparked by the launch of the Script error: No such module "WPSHIPS utilities".Script error: No such module "Check for unknown parameters". and her three sisters in 1858. They were initially armed with a mix of rifled breech-loading and muzzle-loading smoothbore guns, but the Armstrong breech-loading guns proved unreliable and were ultimately withdrawn from service.
The ships spent their first commission with the Channel Fleet before being rearmed with new rifled muzzle-loading guns in the late 1860s. Script error: No such module "WPSHIPS utilities". rejoined the Channel Fleet after her refit while Script error: No such module "WPSHIPS utilities". joined the 1st Class Reserve and joined the fleet during its annual manoeuvres. The two ships exchanged roles after another refit in the mid-1870s. Both ships spent most of the last two decades of the 19th century in reserve. Warrior was hulked in 1902 and survived to be restored in 1979 as a museum ship. Black Prince became a training ship in 1896 and was hulked in 1910 before being sold for scrap in 1923.
Design and description
The Warrior-class ships have been described as revolutionary, but in truth they were more evolutionary than not as everything except their wrought iron armour had been in use by ocean-going ships for years.[1] The naval architect and historian David K. Brown commented, "What made [Warrior] truly novel was the way in which these individual aspects were blended together, making her the biggest and most powerful warship in the world."[1] They were designed in response to Gloire, which started an invasion scare in Britain,[2] but they had a very different concept of operation to the French ship which was meant as a replacement for wooden ships of the line. They were designed by Chief Constructor of the Navy Isaac Watts as 40-gun armoured frigates largely based on the fine lines of the large frigate Script error: No such module "WPSHIPS utilities".. Warrior and her sister Black Prince were not intended to stand in the line of battle as the Admiralty was uncertain about their ability to withstand concentrated fire from wooden two and three-deck ships of the line. Rather they were designed to be fast enough to force battle on a fleeing enemy and to control the range at which a battle was fought for their own advantage.[3]
General characteristics
The Warrior-class ships were Script error: No such module "convert". long between perpendiculars and Script error: No such module "convert". long overall.[4] This was Script error: No such module "convert". longer than the Mersey, the longest wooden-hulled ship in the Royal Navy.[5] They had a beam of Script error: No such module "convert". and a draught of Script error: No such module "convert"..[4] The ships displaced Script error: No such module "convert".. The hull was subdivided by watertight transverse bulkheads into 92 compartments and had a double bottom underneath the engine and boiler rooms.[6]
Two bilge keels were fitted (the first used by the Royal Navy), which significantly reduced the roll of the ships. Because of their length the ships proved to be very sluggish while manoeuvring, as Warrior proved when she collided with Script error: No such module "WPSHIPS utilities". in 1868.[7] The Warrior-class ships trimmed down by the bow, not least because they were fitted with a Script error: No such module "convert". iron knee placed at the bow to give it a traditionally pleasing shape. This also prevented the ships from ramming any other ships. The bowsprit was shortened after completion in an effort to reduce the trim, but it was not noticeably successful.[8]
Propulsion
The Warrior-class ships had one 2-cylinder trunk steam engine made by John Penn and Sons driving a single Script error: No such module "convert". propeller.[9] Ten rectangular boilers[10] provided steam to the engine at a working pressure of Script error: No such module "convert".. The engine produced a total of Script error: No such module "convert".[11] and was the most powerful thus far built for a warship.[12] On sea trials in October 1861 Warrior had a maximum speed around Script error: No such module "convert".; Black Prince was about a half knot slower. The ships carried Script error: No such module "convert". of coal, enough to steam Script error: No such module "convert". at Script error: No such module "convert"..[13]
The ironclads were ship rigged and had a sail area of Script error: No such module "convert".. The lower masts were made of wood, but the other masts were iron. Warrior made Script error: No such module "convert". under sail, but Black Prince could only do Script error: No such module "convert".. Under both sail and steam Warrior once logged Script error: No such module "convert".. Both funnels were semi-retractable to reduce wind resistance while under sail alone. The ships' propellers could be hoisted up into the stern of the ship to reduce drag while under sail. They were the largest hoistable propellers ever made and required about 600 men to be raised.[13]
Armament
The armament of the Warrior-class ships was intended to be 40 smoothbore, muzzle-loading 68-pounder guns, 19 on each side on the main deck and one each fore and aft as chase guns on the upper deck. This was modified during construction to ten rifled 110-pounder breech-loading guns, twenty-six 68-pounders, and four rifled breech-loading 40-pounder guns as saluting guns. The 40-pounder guns were to have been replaced by 70-pounder guns, but these failed their tests and were never issued.[14] Both breech-loading guns were new designs from Armstrong and much was hoped for them. Four of the 110-pounder guns were installed on the main deck amidships and the other two became chase guns; all of the 68-pounder guns were mounted on the main deck. Firing tests carried out in September 1861 against an armoured target, however, proved that the 110-pounder was inferior to the 68-pounder smoothbore gun in armour penetration and repeated incidents of breech explosions during the Battles for Shimonoseki and the Bombardment of Kagoshima in 1863–1864 forestalled plans to completely equip the ships with the 110-pounder gun.[15]
The Script error: No such module "convert". solid shot of the 68-pounder gun weighed approximately Script error: No such module "convert". while the gun itself weighed Script error: No such module "convert".. The gun had a muzzle velocity of Script error: No such module "convert". and had a range of Script error: No such module "convert". at an elevation of 12°. The Script error: No such module "convert". shell of the 110-pounder Armstrong breech-loader weighed Script error: No such module "convert".. It had a muzzle velocity of Script error: No such module "convert". and, at an elevation of 11.25°, a maximum range of Script error: No such module "convert".. The shell of the 40-pounder breech-loading gun was Script error: No such module "convert". in diameter and weighed Script error: No such module "convert".. The gun had a maximum range of Script error: No such module "convert".[16] at a muzzle velocity of Script error: No such module "convert"..[17] The 110-pounder gun weighed Script error: No such module "convert". while the 40-pounder weighed Script error: No such module "convert".. In 1863–1864 the 40-pounder guns were replaced by a heavier version with the same ballistics. All of the guns could fire both solid shot and explosive shells.[18]
Both ships were rearmed during their 1867–1868 refit with a mix of 7- and Script error: No such module "convert". rifled muzzle-loading guns. Warrior received twenty-eight 7-inch and four 8-inch guns while Black Prince received four fewer 7-inch guns. Both ships received four 20-pounder breech-loading guns for use as saluting guns.[12] The shell of the 15-calibre 8-inch gun weighed Script error: No such module "convert". while the gun itself weighed Script error: No such module "convert".. It had a muzzle velocity of Script error: No such module "convert". and was credited with the ability to penetrate a nominal Script error: No such module "convert". of wrought iron armour at the muzzle. The 16-calibre 7-inch gun weighed Script error: No such module "convert". and fired a Script error: No such module "convert". shell. It was credited with the nominal ability to penetrate Script error: No such module "convert". armour.[19]
Armour
The Warrior-class ships had a wrought-iron armour belt, Script error: No such module "convert". thick, that covered Script error: No such module "convert". amidships. The armour extended Script error: No such module "convert". above the waterline and Script error: No such module "convert". below it. 4.5-inch transverse bulkheads protected the guns on the main deck. The armour was backed by Script error: No such module "convert". of teak. The ends of the ship were left entirely unprotected which meant that the steering gear was very vulnerable.[12]
Construction
The gun ports of the Warrior-class ships were built Script error: No such module "convert". wide, which allowed the 68-pounders to traverse 52°. While the ships were being built the directing bar was developed which consisted of an iron bar that fastened to a pivot bolt in the sill of the gun port. After the gun carriages were modified, this allowed them to pivot much closer to the gun port than had previously been possible and meant that the gun ports could be narrowed to a width of Script error: No such module "convert". while retaining the same arc of fire.[20] The gun ports were narrowed to the new width by Script error: No such module "convert". of wrought iron.[6] Another delay was the modification of the armour plates with tongue and groove joints to lock the plates together and increase their resistance to armour-piercing shells. All together these modifications delayed the completion of Warrior by a year past her contract completion date.[5]

Service
HMS Warrior joined the Channel Fleet in July 1862 and was placed in ordinary from 1864 to 1867, during which time she was refitted. The ship rejoined the Channel Fleet in 1867 and towed a floating drydock to Bermuda in 1869 with her sister Black Prince.[23] Warrior was placed in ordinary again from 1872 to 1875 and was modified with a poop deck. She was recommissioned into the 1st Class Reserve in 1875 and made periodic training cruises until 1883.[23] The ship was formally reclassified as an armoured frigate in 1884,[24] but was disarmed and mastless. Warrior was hulked as a depot ship in Portsmouth Harbor in 1902 and renamed Vernon III in 1904 when she became part of Script error: No such module "WPSHIPS utilities"., the Royal Navy's Torpedo School. The ship regained her original name in 1923 and was converted once more into an oil pipeline pier in 1927. Warrior was towed to Pembroke Dock in 1929 and was renamed C77 in 1942 to release her name for the new aircraft carrier Script error: No such module "WPSHIPS utilities".. In 1979 C77 was moved to Hartlepool and was restored as HMS Warrior (1860) as the Fleet Headquarters in Northwood, London had assumed the name of HMS Warrior in the early 1960s. The ironclad can now be seen near Script error: No such module "WPSHIPS utilities". at Portsmouth Historic Dockyard.[25]
Black Prince capsized while in dock at Greenock, damaging her masts. She arrived in Spithead in November 1861 with only jury-rigged fore and mizzenmasts.[23] The ship was assigned to the Channel Fleet upon her completion and in 1867–68 she was rearmed and then assigned to the 1st Class Reserve. She was refitted in 1874 and given a poop deck, and rejoined the Channel Fleet in 1875 as the flagship of Rear Admiral Sir John Dalrymple-Hay, second in command of the fleet. Black Prince was placed in reserve in 1878 in Devonport until she was converted to a training ship in 1896 in Queenstown, Ireland and renamed Emerald in 1903. The ship was hulked and renamed Impregnable III in 1910 when she was assigned to the training school Script error: No such module "WPSHIPS utilities". before she was sold for scrap on 21 March 1923.[26]
